Abstract

In order to provide a functional component mounting base having high durability to an inertial force acting on a functional component when a tire engages with and disengages from the road surface and to an impact force acting on the functional component mounting base when the tire passes over bumps the functional component mounting base (1) is formed of a rubber material, is attached to an inner surface (70) of the tire to mount the functional component (29) on the inner surface (70) of the tire, and characterized by being provided with a fitting recess (2) into which a functional component-side attaching portion (30) provided on the functional component (29) is fitted. The fitting recess (2) is formed such that an opening diameter of an opening (3) to the fitting recess is smaller than a maximum diameter of the functional component-side attaching portion (30), an inner surface (inner peripheral surface (9)) of the fitting recess (2) is formed as a fitting surface that fits with an outer surface (outer peripheral surface (31)) of the functional component-side attaching portion and a bottom of the fitting recess (2) is formed as raised and recessed portions (semicircular projections (5, 6) and a partition recess (8)) which fit with recessed and raised portions (semicircular recesses (34, 35) and a partition projection 33) formed on the functional component-side attaching portion (30).
